Background: Throughout the past few years, numerous Medium Access Control (MAC) protocols, routing protocols, node deployment mechanisms and duty cycle variation schemes have been designed for achieving high throughput, low delay and jitter, and long network lifetime in Wireless Sensor Networks (WSNs). In a WSN with static sink, voluminous sensors transmit their sensed data to the sink node. The coordinators mutually present in the range of sensors and sink have to forward a number of packets, which cause rapid depletion of their battery. These coordinators become dead too early resulting in the breakage of the communication channel and formation of energy holes. However, to save energy with a static sink, the duty cycle should be short. A mobile sink is a better option than a static sink if the duty cycle is long, as it balances energy consumption among the sensors. It is well observed that the mobile sink is capable of acquiring homogeneous energy depletion leading to stretched lifetime enhancing network performance. Methods: The vital benefaction of this paper is to present a simulation-based analysis of the network performance with a mobile sink having different trajectories of path traversed at different velocities. The intent is to find out the most appropriate and efficient trajectory and a particular velocity for a specific WSN with 100 nodes. The terrain area of the network is 210×210 m2 with the communication range of 20 m. The routing, network and MAC protocols implemented are Ad hoc On-Demand Distance Vector (AODV), Internet Protocol version 4 (IPv4) and Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 respectively. This paper has evaluated and analyzed the influence of lawn mower, elliptical and circular trajectories of a mobile sink moving at different velocities of 0.5, 1 and 2 m/s. The optimum performance is achieved at the velocity of 2 m/s for a circular trajectory of the mobile sink. It is observed that performance has significantly varied with the variation of trajectories and velocities. The notion of precise utilization of sink mobility improves the performance than a static sink. It is equally important to determine the most effective mechanism to implement mobile sinks and to find out the most appropriate scheme out of them. Results: The attainment parameters just as total messages received, average end to end delay (seconds), jitter (seconds), throughput (bits per second), number of packets dropped, number of packets dropped due to channel access failure, residual battery (mAh) and network lifetime (hours) for different trajectories such as lawn mower, elliptical and circular at different speeds of 0.5, 1 and 2 m/s of the sink node are evaluated and compared. The simulation results present that the circular trajectory and the velocity of 2 m/s have provided optimum performance. Conclusion: The objective was to precisely analyze and evaluate the influence of different trajectories of a mobile sink moving at different velocities in a WSN of 100 nodes to determine the most effective and appropriate trajectory and velocity to optimize the attainments. The intent is to uniform the power exhaustion amidst the sensors. The purpose was to gain the attention of researchers of this field to significantly contribute to novel research.

ZigBee is recently developed technology which can be implemented in IEEE 802.15.4 standard for a wireless sensor network (WSN). It is specially made for the purpose of control and sensor network and comprises of ZigBee Coordinator, router and end devices. It has low information rate, low power utilization and economical value, which are principle highlights of ZigBee. The network topology may include star, cluster tree or Mesh. The sensor nodes transferring data in the network is generally sent to the coordinator, the coordinator collects sensor information, stores the information in memory, process the data, and direct it to proper node. In this paper, this work is related to the impact of increase in ZigBee Coordinators on a 3D terrain in both static and mobile condition of sink node, to determine its optimum performance. The use of Archimedes' Spiral was introduced to mobility pattern to study its resultant simulation performance metrics.

Background: Wireless Sensor Network (WSN) is among the most promising technologies that can be used to monitor crucial ambient conditions. WSNs are capable of effectively monitoring the environmental parameters and any habitat necessary to be investigated. Sometimes, it is very important to periodically monitor the critical environmental parameters such as humidity, temperature, soil moisture, fire, volcanic eruptions, Tsunamis, seismic waves and many more to react proactively to save lives and assets. This research work is an endeavor to present the importance and to determine the precise inter- nodal distance required for distinct applications. The networks of the different terrain area and internodal distance are deployed to evaluate and analyze the performance metrics such as a number of messages received average end to end delay (secs), throughput (bps) and jitter (secs). The influence of varying inter-nodal distance on the performance of WSN is determined to select the most appropriate value of the distance between nodes in particular monitoring application. The patents related to the topology based analysis of wireless nodes are reconsidered. Methods: The placement of nodes and inter-nodal distance significantly influences the operation and performance of WSNs by diverging the ability of sensors to observe an event of interest and transmission of information to data aggregation nodes (sink nodes). Moreover, effective sensor placement also affects the resource management. The investigation of specific regions and habitats has peculiar constraints of node placement and inter-nodal distance making it highly application specific. In this research work, the intent is to monitor an entire area to attain optimum coverage to detect the occurrence of a significant event. The node placement and inter-nodal distance can be classified on the basis of the role played by the deployed nodes, like, placement of ordinary sensor nodes/Reduced Function Devices (RFDs) and relay nodes/Full Function Devices (FFDs), respectively. The sensors are compatible with IEEE 802.15.4/ZigBee protocol and application implemented is Constant Bit Rate (CBR) generator. This paper analyzed and evaluated the influence of placement and inter-nodal distance of RFDs to the data aggregation ability of sink node. The terrain area (m2) of different sensor networks deployed are 110×110, 200×200, 300×300, 400×400 and 500×500, respectively. The number of sensor nodes is constant equal to 100 to evaluate their ability to provide optimum performance. The parameter internodal distance is varied, keeping all other parameters constant to effectively evaluate its influence. The simulations are carried out on QualNet 6.1 simulator. Results: The variation in inter-nodal distance significantly influences the performance metrics of the network such as the number of messages received, average end to end delay, throughput and jitter. In this paper, the distance between sensor nodes and terrain areas of grid topology is varied accordingly to deduce that which value of the inter-nodal distance and network provides optimum performance. The thorough evaluation of the simulation results presented that the inter-nodal distance of 30 m and terrain area of 300×300 m2 has generated optimum performance by providing the highest number of messages received (208) and highest throughput (2544.34 bps). It is also capable of providing minimum end to end delay (14.45 secs) and lowest jitter (6.67 secs). Conclusion: The objective of this paper to determine the optimum inter-nodal distance and terrain area of a WSN of 100 nodes is successfully achieved. It is analyzed and evaluated that the inter-nodal distance of 30 m and terrain area of 300×300 m2 enhance and optimize the network performance significantly.

Background: This paper proposes a novel MultiChannel Caucus based Medium Access Control (MC2-MAC) protocol to diminish collisions between different data packets to reduce energy dissipation of nodes and latency of data packets transmitted by the sensors communicating in Line of Sight (LOS) communication deployed to supervise distinct raucous provinces in the smart grid. Methods: The performance diminishing major problems such as wastage of battery power, bottlenecks and collisions need to be mitigated to elongate lifespan and to diminish data latency. The employment of caucus based efficient scheduling scheme enhances synchronization and multiple channels prevent collisions by reducing the number of contending nodes. The utilization of multiple channels enables sink node to communicate simultaneously with numerous nodes. Results: The influence of multichannel is evaluated by comparing the simulation results of the networks implementing ZigBee, C-MAC and MC2-MAC protocols. QualNet 6.1 simulator is used to perform the simulations. Conclusion: The work resolute to evaluate and correlate the impact of the multichannel scheme to optimize the performance metrics of sensors deployed in distinct raucous provinces communicating in LOS environs in the smart grid and to gain the attention of scholars in this emerging field of research.

A ZigBee communication technology is established recently for several smart electric grid applications like Home Energy Management Systems (HEMS), Electric Vehicles (EVs), wireless automatic Metering, load control, fault detection and power outages. Analysis is done to investigate the performance of ZigBee in terms of throughput, packet delivery ratio, average delay and energy consumed in various three dimensional smart electric grid environments which includes an outdoor 500KV substation, an underground network transformer vaults and an indoor power control room. We are considering three dimensional sensor node deployments as more practical in the real world. From our simulation results it is seen that IEEE 802.15.4 based ZigBee is best suited for smart electric grid applications which are having less reliability requirements.
